Cold Rolled Automotive Steel B250P1E+Z steel and strips are featured with good erosion-resistant, high surface quality(O5 plate surface are available) and excellent processing and coating performances. They can be used to manufacture inside an outside automotive plates , structural parts and reinforcements.

Cold Rolled Automotive Steel B250P1E+Z steel plates mechanical and process performances:
Among the mechanical performances of Zn-Ni alloy coated plates/strips, breakage percent elongation is allowed to be lowered by 2 units against that of relevant base plates, r is allowed to be lowered by 0.2 against that of relevant base plates and other mechanical and process performances shall comply with the stipulations of those of relevant base plates.

Cold Rolled Automotive Steel B250P1E+Z steel plates coating bending test:
Steel plates and strips for cold forming purposes are subject to coating bending test. There are no coating strips on the outside surface of a sample( at the spot over 7mm away from two edges of the sample), which is bended by 180 degrees in any direction. Refer to provisions of relevant base plates for bending center diameter and take 0a as the bending center diameter in case of no requirements by the base plates for it.
